@Chicoro The L'Oréal Steampod I have is like this. Instead of being glued, it has its own special slot to slide it in or out.
At first I removed the comb, but as my hair became more damaged and harder to straighten out the 'kinks,' it was invaluable. Got my hair super straight with the comb and the steam. I love it. Here's what it looks like. And, FYI, the steam output is exaggerated in this pic. It is much more faint and subtle.
I have the Maxiglide too, but always felt the spikes caught on my hair too much (maybe because they were sporadically placed on the plate?). So, I always used it without. I still loved that flat iron though.
